26possible. Contract provisions incorporating the above
requirements must be included as part of the project's
construction documents, which must be reviewed and approved
by the Planning and Building Safety Department.
MM4.3 -4 The developer must require by contract specifications
that heavily loaded trucks used during construction must be routed
away from residential streets to the extent possible. Contract
specifications must be included in the proposed project
construction documents, which must be reviewed by the City
before grading permits are issued.
MM4.3 -5 Residential units must be designed and constructed to
ensure that interior noise levels from exterior transportation
sources — including aircraft and vehicles on adjacent roadways —
cannot exceed 45 dBA CNEL. In order to ensure that all dwelling
units achieve an adequate noise reduction to achieve an interior
noise level of 45 dBA CNEL, the following features must be
included in the building design and construction of all dwelling
units: (1) upgraded dual - glazed windows, (2) mechanical
ventilation /air conditioning, (3) exterior wall /roof assemblies free of
cut -outs or openings, and (4) ceiling insulation in the top floor of
each building to reduce aircraft noise by at least 20 dBA. Before a
building permit is issued, the developer must submit architectural
plans and a detailed acoustical analysis study prepared by a
qualified acoustical consultant demonstrating that interior noise
levels in all residential units would be 45 dBA CNEL or less to the
Planning and Building Safety Department for review and approval.
C) Finding:
The City Council finds that with implementation of identified
mitigation, potentially significant noise impacts (as identified
above) would be reduced to a less- than - significant level as
identified in the FEIR.

a) Facts /Effects:
(1) Emergency Access. Implementation of either Option of the
proposed project would not result in inadequate emergency
access. However, to ensure that either Option of the proposed
project would not result in inadequate emergency access, site
plans, site construction, and the actual structures would be subject
to review and approval by the El Segundo Fire Department before
building occupancy to ensure that required fire protection safety
features, including building sprinklers and emergency access, are
implemented. Additionally, implementation of mitigation measure
MM HAZ -4 would ensure that emergency response teams for the
City of El Segundo, including the El Segundo Police Department
and El Segundo Fire Department, would be notified of lane
closures during construction activities in the project area and that
